Description

Linear slide with oil scraping and dustproof structure

The invention is a linear guiding element, in particular a linear sliding rail with a dustproof sheet.

According to the continuous development and improvement of precision feed systems, linear slide technology and its products have become the most important part of many precision machines. Various linear mechanism products have been widely used in human life, processing factories and high Within the technology equipment, although the development of linear slide technology is very rapid, consumer users still need continuous improvement of technology, so it also produces many problems that linear products (such as linear slides) are still to be developed, and related technology industries. They are also actively developing new creations and new inventions that can effectively improve linear slide technology; especially on many high-precision manufacturing industry tools that require more stable and quiet (eg wafer processing equipment, CNC equipment, etc.) Therefore, there are still a number of blind spots in the current linear mechanism technology, which is extremely urgent for people from all walks of life to add research and development.

There are two types of linear slide lubrication methods commonly used on the market: First, the forced oil (fat) oil supply system: the use of a fuel injection pipe and the end cover of the slider on the linear slide rail, after timing quantitative Supply lubricating oil (fat). Second, the lubricating oil (fat) supply method: the end cap of the slider mounted on the linear slide rail by a grease injection joint, and the lubricating oil in the oil gun is connected with the joint by a grease gun (Fat) is injected into the end cap to lubricate the lubricating oil (fat) in the end cap.

The above two lubricant supply methods are driven by the linear slide rails. Lubricating oil (fat) flows, so when the lubricating oil (fat) overflows the outside of the end cover or the slider, it will cause problems that pollute the surrounding environment of the machine or insufficient lubrication; therefore, it is necessary to improve.

Based on the foregoing problems, the present invention develops a scraping oil structure that can drive lubricating oil (fat) to flow in the direction of the rolling groove when the slider is in operation to avoid loss of lubricating oil (fat) and cause insufficient lubrication or environmental pollution. The problem arises.

The invention relates to a linear slide rail with a scraping oil and dustproof structure, comprising: a rail strip extending into a long strip structure in one direction, defining the extending direction as an axial direction; a slider module, a sleeve sleeve The rails are reciprocally displaceable in the axial direction, and the slider module is respectively provided with a dustproof piece at both ends of the axial direction, and the two dustproof pieces respectively have lips corresponding to the outer shape of the rail, and the two lips are respectively Contacting the surface of the rail, and the two lips are provided with a plurality of scraping recesses, each of the scraping recesses having two outer ends and an inner end to form a triangular structure, and each of the two dustproof sheets The two outer ends of the oil scraping recess are respectively arranged in a staggered manner, and the outer ends are defined as openings, and the openings of the two dustproof sheets are opposite and staggered.

Referring to the first to fifth figures, which are diagrams of a preferred embodiment of the present invention, the present invention is a linear slide rail having a scraping oil and dustproof structure, comprising: a rail (1) , extending in a direction to a strip-like structure, defining the extending direction as an axial direction (X), the two sides of the axial direction (X) respectively having a side surface (11), the side surface (11) being respectively provided with a first Rolling groove (111), one side of the first embodiment is provided with two first rolling grooves (111), a total of four; a slider module is sleeved on the rail (1), which can be oriented in the axial direction ( X) Reciprocating displacement, the slider module comprises: a slider (2), two end covers (3) and two dustproof sheets (4), the slider (2) is provided opposite to the first rolling groove (111) a second rolling groove (22), a plurality of rolling elements (not shown) are disposed between the first rolling groove (111) and the second rolling groove (22), and the linear sliding track of the embodiment is rolling The slider module is moved relative to the rail. However, the dustproof sheet (4) of the present invention can also be used for a linear slide without a rolling element, which is commonly known as a hard rail in the industry; the end cover (3) Set at the ends of the axis (X) of the slider (2), and The dustproof sheets (4) are respectively stacked on the two end covers (3), and the two dustproof sheets (4) respectively have a lip portion (41) opposite to the outer shape of the rail (1), and the two lips (41) Is in contact with the surface of the rail (1), and the two lips (41) are provided with a plurality of scraping oil recesses (411), each of the scraping recesses (411) having two outer ends (4111) and one inner portion The end (4112) constitutes a triangular structure (Note: the scraping oil recess may be rectangular or semi-in addition to the triangular configuration Round, semi-elliptical or curved); please refer to the fifth figure again, the spacing indicated by (X) of the fifth figure is clearly understood, and the scraping recesses (411) of the two dustproof sheets (4) are The two outer ends (4111) are respectively arranged alternately with each other, and the two outer ends (4111) are defined as openings (4113) of the oil scraping recesses (411), which can be clearly seen from the first figure, and then In the five figures, it can be seen that the openings (4113) of the two dustproof sheets (4) are opposite and staggered, and such a design can drive the lubricating oil (fat) toward the first rolling groove (111) and the second rolling groove. (22) Direction operation, which is described in detail below.

Please refer to the sixth to seventh figures, which are diagrams showing the state in which the lubricating oil (fat) is driven in the direction of the first rolling groove (111) and the second rolling groove (22) when the two pieces of the dustproof piece (4) are operated. When the slider module moves, because the lip portion (41) is in contact with the surface of the rail (1), by the arrangement of the scraping oil recess (411), the two dustproof sheets (4) are opposed to the rail. (1) When the surface is displaced, as shown in the sixth figure, the slider module moves to the right, and the scraping recess (411) of the left dustproof sheet (4A) is the surface of the rail (1). After the lubricating oil (fat) (5) is brought in (as an example of a scraping oil recess, in fact, each scraping oil recess has lubricating oil (fat)), and runs to the slider module to the right to stop. At the moment when the slider module moves to the left, the lubricating oil (fat) (5) in the scraping recess (411) of the left dustproof sheet (4A) will stay in place, but because of the slider module The running direction is opposite to the opening (4113) of the scraping recess (411) of the left dust guard (4A), so the scraping recess (411) of the left dust guard (4A) can no longer retain the lubrication. Oil (fat) (5), then see FIG seven, dustproof sheet right (4B) passes through the operating oil (fat) (5) harborage, will bring the oil (fat) (5) scraped In the oil recessed portion (411), it is known that the opening (4113) of the scraping oil recess (4) of the left side dustproof piece (4A) and the right side dustproof piece (4B) is staggered, so that the lubricating oil is caused (Fat) (5) After a few times of the left and right dustproof sheets (4A, 4B), the moving upwards of the rails (1) are gradually concentrated on the first rolling groove (111) and the second rolling groove (22). That is, the object of the invention is achieved to make the lubrication of the linear slide more sufficient.

In view of the above, the "industrial availability" of the present invention should be unquestionable. In addition, the feature technology disclosed in the embodiment of the present invention has not been seen in publications before the application, nor has it been disclosed. The use of not only has the fact that the effect is improved as described above, but also has an additional effect that cannot be neglected.
